Testing under real-world conditions is key for reliability, especially with MU-MIMO where poor beamforming decisions by the O-DU can impact performance.
MU-MIMO lets multiple User Equipment (UEs) share the same time and frequency resources without interference. By separating signals spatially and applying beamforming, gNBs enhance spectrum efficiency.
A well-tuned scheduling algorithm can boost throughput for multiple UEs at once, enhancing both customer experience and spectrum efficiency. This means maximum ROI for service providers. But if channel estimation or beamforming weights are off, you risk high interference, lower throughput, and poor QoS.
Because complex gNB algorithms can cause issues, running worst-case scenario checks is a smart move. For real-world accuracy, test MU-MIMO under imperfect conditions.
Skip the complex, costly RF setups. Instead, use a digital O-RAN Front Haul (FH) interface to test MU-MIMO. Emulate UEs and O-RUs, connect via eCPRI, and you’ll be able to assess MU-MIMO and O-DU performance before rolling out real O-RUs.
With the right testing solution tailored to your needs, you’ll hit peak efficiency with your MU-MIMO solutions.
